I am getting married on Dec. 22, 2012. I am interested in having our wedding party picked up from the ceremony site and dropped off at the reception site. Both locations are downtown Grand Rapids and are less than 1 mile apart. We will need the shuttle/bus for less than one hour. There are approximately 20 people in our wedding party. Any suggestions for affordable transportation? I have been calling limo and party bus rentals but haven't found anything under $400. And the GR Hopper is closed that weekend due to the holiday. Please help!
